..Previous studies have shown that polybrominated diphenyl ethers (PBDEs) behave as weak estrogens in animal and cell culture bioassays. In vivo metabolites of PBDEs are suspected to cause these effects...

Hydroxylated metabolites of polybrominated diphenyl ethers in human blood samples from the United States

..A previous study from our laboratory showed that polybrominated diphenyl ethers (PBDEs) were metabolized to hydroxylated PBDEs (HO-PBDEs) in mice and that para-HO-PBDEs were the most abundant and, potentially, the most toxic metabolites...

..Analyses of the relative distributions of the most abundant PBDE congeners (using category averages and principal component analysis) indicated that these patterns cannot yet be used to assign sources to these pollutants...

Global assessment of organic contaminants in farmed salmon

Ronald A HitesSchool of Public and Environmental Affairs, Indiana University, Bloomington, IN 47405, USAScience 303:226-9. 2004

..Risk analysis indicates that consumption of farmed Atlantic salmon may pose health risks that detract from the beneficial effects of fish consumption...

..43, and 0.20 ng cm(-2) yr(-1), and the inventories were 0.87, 3.9, and 1.8 ng cm(-2) for PBDE3-7, BDE-209, and TBE, respectively. The concentration of DP in Lake Ontario sediment exceeds that of the brominated flame retardants combined...

Effects of wind and air trajectory directions on atmospheric concentrations of persistent organic pollutants near the Great Lakes

..A simple one-dimensional, Gaussian diffusion model was used to explain the spatial distribution of DP and to locate the source. The calculated source location was <7 km away from the DP manufacturing plant in Niagara Falls, New York...

..These results help explain the deposition patterns of PBDEs found in lake and river sediments and have important implications concerning the inclusion of photolysis as a fate process in multimedia models...

Atmospheric organochlorine pesticide concentrations near the Great Lakes: temporal and spatial trends

..These positive relationships indicate that the replacement of the deca-BDE commercial product by DBDPE and the penta-BDE product by Firemaster 550 have not yet become evident in the Great Lakes' atmospheric environment...

..We estimate [corrected] the total burden of these compounds in all of the Great Lakes is on the order of 100 [corrected] tons. In both lakes, BB-153 was found to increase rapidly during the 1970s and to peak around 1980...

Identification of brominated carbazoles in sediment cores from Lake Michigan

..None of these compounds were more abundant in the AVM affected sediments and tissues than in the unaffected media. Therefore, it is unlikely that any of these compounds are the cause of this avian disease...

Radical dependence of the yields of methacrolein and methyl vinyl ketone from the OH-initiated oxidation of isoprene under NO(x)-free conditions

Temporal and spatial trends of organochlorine pesticides in Great Lakes precipitation

..Backward trajectories for air masses with high concentrations of deca-BDEs coming to the Arkansas site suggestthat deca-BDEs bound to particles can move long distances from source regions to nonsource regions...

Post-1990 temporal trends of PCBs and organochlorine pesticides in the atmosphere and in fish from lakes Erie, Michigan, and Superior

..The most rapid temporal trend was observed for α- and γ-HCH concentrations, which are decreasing in both the atmosphere and in fish with halving times of 3.3 ± 0.4 years. The practical implications of these results are discussed. ..

Differences in spatiotemporal variations of atmospheric PAH levels between North America and Europe: data from two air monitoring projects

..The Arrhenius parameters here are the first to be reported. The reactions of α- and β-farnesene with OH showed no significant temperature dependence. Atmospheric residence times due to reactions with OH and O₃ were also presented...

Temporal trends of polychlorinated biphenyls in precipitation and air at chicago

..However, retene concentrations in precipitation collected at the Lake Superior site were higher compared to Lakes Michigan and Erie, which indicate more residential wood burning in the far north of the Great Lakes basin...

..PEB was not found in the sediment core from Lake Michigan. These occurrences of relatively high concentrations of TBE and PEB in environmental samples may reflect the increasing usage of these compounds as flame retardants...

Atmospheric transport of toxaphene from the southern United States to the Great Lakes Region

..We also compared the chemical behavior of toxaphene in the atmosphere and found that the congener ratios were similar at the different sampling sites but slightly different from various toxaphene standards...

Temporal trends of persistent organic pollutants: a comparison of different time series models

..8 ± 2.8 years, respectively. For PBEB and DBDPE, the regression was not statistically significant for the combined phases, indicating that the atmospheric concentrations of these compounds have not changed between 2005 and 2009...

Polychlorinated dibenzo-p-dioxins and dibenzofurans in the atmosphere around the Great Lakes

..A statistically significant relationship was found between total PBDE concentrations and total PCB and p,p'-DDE concentrations, suggesting that these compounds share a common source, which is most likely the eagle's food...

..Fish to sediment concentration ratios indicated that the tetra- through hexa-substituted congeners have a similar bioavailability, while the deca-substituted congener does not seem to be bioavailable at all...

..This paper highlights selected long-term monitoring programs and discusses a number of documented ecological changes that indicate the present state of the open and nearshore waters of the Great Lakes...
